Question

4(y+1)-3x+5 при x =-7 у=-2

Answer 1

4(y+1)-3x+5=4у+4-3х+5=4у-3х+9=4(-2)-3(-7)+9=-8+21+9=22

Answer 2

To evaluate the expression 4(y + 1) - 3x + 5 when x = -7 and y = -2, simply substitute the values of x and y into the expression and then perform the arithmetic operations.

Let's do the calculations step by step:

1. Substitute the values of x and y: 4(y + 1) - 3x + 5 = 4(-2 + 1) - 3(-7) + 5

2. Simplify the inner parentheses: = 4(-1) - 3(-7) + 5

3. Perform the multiplications: = -4 + 21 + 5

4. Perform the additions: = 22

So, when x = -7 and y = -2, the expression 4(y + 1) - 3x + 5 evaluates to 22.
